My first experience with a can of air was years ago and it jetted out a stream so cold it caused condensation on my motherboards components! I'm sure 'air technology' in a can has come a long way since then so can you recommend a decent brand to get?
Well if you shake it correctly, it shouldn't be spraying liquid at all. I used the office 5-star ones. They work just fine.
if i blow into a used coke bottle can i send you that ? place a pin hole in the top of the bottle and squeeze and hey presto instant air (T&Cs: not responsible for effectiveness or any sort of actual airflow)
simple: turn off your computer before blowing compressed air at it. the water vapour goes away pretty quickly anyway, nothing to worry about, if your computer is turned off. also, hold your can upright and shake properly. i find those Asda cans will spray a lot of liquid if the can is not hold upright.
Or do what i do take a old spray gun and spray it with a compressor it gets the job done(yes there is no paint in the gun)
When not using the compressor in the workshop (filtered and dried stream, with variable pressure and pen-tip sized nozzle) I use these. They've never produced gas/vapour for me.
There's plenty people here with lots of wind I'm sure one of then could fill a can for you lol But seriously I use a compressor I just turn the pressure down to a lower level.
The "dust off" "gaming Gear Duster" is good. Bit it's even better if you combine it with a henry hover and the small brush attachment. No point it just blowing the dust around, you want to suck it out as well.

I found compressed air to be really ineffective. Bought a can when rebuilding my computer and it did not shift any of the caked on dust from fan blades etc. In the end I went for q - tips and wiped everything clean inch by torturous inch!
When using canned "air" be careful to keep the can upright, especially when it's new. If you tilt the can, the liquid gas in the can will be sprayed out, which evaporates quickly and causes condensation. PRF 4-44 works well. It won't last very long, but at least it's effective. Those super cheap cans of compressed air may give of air longer, but they really don't work at all. The gas used in cheap cans also have a tendency to evaporate less when the can gets cold from use. This makes it even less effective... In the long run a small compressor is probably better and cheaper, though. (Besides, it can be used for more than just cleaning computers) And why do people shake these cans of "air"? That doesn't help at all, if anything it could cause the liquid inside the can to come put of the nozzle, which will cause condensation on the thing you are spraying. Never, ever use a vacuum cleaner in a computer. They build up a hell lot of static electricity when in use. Not something you want near any electronic equipment. You can hold the vacuum cleaner near the case to catch the flying dust from the compressed air, but simply carrying your computer outdoors is easier and more effective.
1" paint brush + vacuum cleaner > all. Unless of course like me, you have a stupidly big compressor that would blow the SMD components off the board if you gave it half a chance.
found a nebulizer with a custom attachment works good too.. the thing with compressor is water builds up and if you don't drain it regular- sprays out the nozzle as vapor just something to look out for
